Child taken away for neglect when not neglected

I figured out the problem, although it took some work. When my child aged up to a toddler, I accidentally aged her up to a child as well. So I de-aged her with the console back to a toddler. When she aged up to a child normally, she started off in school as an F student. Which apparently is enough to have your kid taken away from you. Frustratingly, she was given extra homework over the weekend that she kept getting taken away to get her grades up. There was no warning that this would happen either, so I was pretty annoyed. I had to use the console to put her grades up to a D.
